Abstract: The ability to rapidly probe the mechanical properties of complex fuids under flow conditions is key to (i) understanding how products respond to imposed flows, (ii) studying how changes in product formulation affect manufacturability and (iii) in the development of advanced rheometric techniques for process control applications. However, attempts to characterise the rheological properties of such materials, and their microstructural response to an imposed flow condition, using superposition rheometry can be hindered where the material is undergoing a rapid microstructural evolution or where high value materials are involved in the product formulation. Herein, the use of Fourier Transform Mechanical Spectroscopy operated with a superposed parallel stress (termed Fourier Transform Controlled Stress Parallel Superposition, FT-CSPS)is validated and deployed on a series of gelling and high value materials of industrial relevance.
